-Be it known that I, CLARENCE Rican, a citizen ofthe United- States, residing at Hudsom'in the county of Lenawee,

State of Michigamy have invented certain new and useful 'Improvements 1n Cement CJI Culverts; and I do hereby declare' the .following lto be a full, clear, and eXact description of the invention, such as willenable others skilled in' the art to which it appertains to maire and use/the same.

This invention has relation to cement culverts for use in. any place to which they may be suited, but especially for railways 'and highways, Where high engineering skill is not readily attainable for setting them up or putting them in right and efficient positions.

The nature of the invention is embodied in the means illustrated in the` accompany# ing drawing, in vi'eW- of Whichit will first be described with respect to its construction and mode of employment and thenl be pointed o ut in the subjoine'd claim.

0f the said drawings-Figure l is a top View of a sect-ion of my improved culvert. Fig. 2 is a longitudinal sectional view. Fig. 3 is a. transverse sectional view 'of my culvert.. Fig. et is a perspective View of one of the base sections. F ig. 5 is perspective view of a. cap piece, While, Fig. 6 shows one of the cement cords.l

' Similar characters of reference designate similar parts or features, 'as the case may he, Wherever they occur. 1

In the drawings 2 designates a 'seotion of my improved culvert constructed With a h'al'f round depression 3 extending longitudinally in its upper side which is in! tended to constitute half .of the opening through the culvert. The sides 'i of the depression will be properly built up2 and their upper edges will be provided with a half round groove' for the reception' of cement cord 5, to be presently more speciiically described.` The bottom of the base-,section is flared outwardly at each side, as at 6, the said iiared The hase sections will ordinarily be made about two feet in length. and each section will have cast therein at intervals of about one foot a half round supporting or reinforce bar of iron or steel as large as the circumstances may call for.

8 designates a cap section of thesaine length as. the base section and made in the same way excepting that the depression to A. VAN

part actinef as a brace to the sides. i

form the opening is reversely 'curved and the top is .likewise curved reversely, omitting the flared loase.-

In the construction of a `culvertthebase sections will break joints with the cap sec-1 tions, and therefore the beginning of thi-.

building of a culvert may take but a haltI` cap section. in length and end in the same way, as sho in, but the half-round steel -reinforce bars will-be cast'in the cap sections in such position thatvtheir ends will, meet the ends of similar bars and thus practically form-reinforcing bars of steel in the form ofuringsin the cement.

The upper edge-ges oie-the sides ofthe base sections as. Well vas the lower edges of the cap sections will have half-round grooves made there-in, as indicated, to receive the tie cement cord 5 when the sections are put toget'her, in building a culvert. The said cord is continuous, and being independent of the sections, may be composed of any suitable material that will not only hold the sections in place and preserve the continuity of the. joints, but constitute` a device. to which the ends of the sel'nicircnlar reinforcing rings mayjbe connected to preserve'their position and continuity. (See particularly Figs. 3 and et.) Each section' is provided. with recesses l0 for the reception of the ends of lifting instruments to facilitate putting them into place. The recesses for the lifting instruments as `will benoted come opposite the reinforcing bar 7, so that danger of lthe fracin the base sections,

ture of the sections bythe pressure/of the lifting instruments is obviated, as the reinforcing elements are disposed at the points Where the greatest strains occur. 'This is an important feature of the invention and adds materially to its etlieiency and utility.

By my improvemeits a very strong, etticient and ,economical 4culvert may beconstructed, and' one, while. requiring good'intelligence in seeing'that it is properlymade, does-not call for lngh engineering skill in its, construction.

From the ized that there is provided a sectional culvert which may be quickly set, byireason of the fact that the surface' upon which it is placed requiresno special preparation' other than toE be madeI substantially level. The earth that is filled upon the culvert, gravitates a ainst the concaved ortions of the sides ofthe base member, and holds the base member against tilting ,and consequent opentlin of thejear agnst' the-conc` member.
